 Great that everyone enjoyed the course so much. Keep it material. Hi, Professor Mark and Carla, thanks so much for the course. It is very helpful to me. It's been such a great experience sharing with you this course and a study about the seal. I really enjoyed it. I liked the two-week format. This course tells a story of where it still comes from. If you asked me how much your course is, I think it is very related with my background. Hi, this is British Romania. My name is Rudein Risto. I'm from Damascus, Syria. Hi, I'm Alison Gash. I work in Canada. I roll world. I try to save. Your course is very attractive and fun. I found myself thinking about steel in my day-to-day life. Steel can be explained in this simple way. In this course, everything has been explained. For example, smelly composition process. Especially those small videos of one minute, two minutes, three minutes at maximum of your course. And the simulations are excellent. I love the professor. I love the subjects. And special thanks to the professor. The videos are very short and it gives you the opportunity to search more, to be more curious. Hope for being boring. It helps me in my training, in welding. Really quick video clips. Very engaging. I really liked the MOOC. I enjoyed while learning and that's why I would recommend it to everyone. I hope there is another course from you. Thank you for all of you who prepared such a nice and wonderful course. Thank the sponsors of this course. And I offer best wishes to all the students here. Thank you very much for the course. It was very good and we keep stealing our life. Keep it in my day-to-day life. It's so much interesting doing an introduction to steel. This is my washing machine and it's like one instructor joined us. And it's made of steel. Toiletieroom. Here's my beloved washing machine. It's made of steel. I wanted to thank you. And I feel I will successfully introduce to steel. Thanks a lot for being part of this course.
